The link you gave points to the tutorial for doing what you want to do.

That is the way to do it. There isn't a better approach. So the only advice that we can give is to recommend that you try again paying closer attention to ensuring that you do exactly what it says (hint: the symptoms that you describe can occur if an apostrophe is missed out).

OK I have tried again from scratch
here is what it looks like now have just used test as a trial
is this right
thanks

OK found out how to do it
it was
includes/languages/english/my site/meta_tags.php
I was changing the english and not my template file under english
